TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 553,074, dated January 14, 1896.

Application tiled September 3, 1895. A Serial No. 561,256. (No model.)

of the pipe-stem, and whereby the mixture of such moisture with the nicotine and the consequent adhering of the mixture to the Walls of the smoke-passage to clog the same are prevented.

A further object of the invention is to provide a device, in connection with a pipe-stein or the mouthpiece thereof, whereby the entrance of the moisture from the mouth of the user will be prevented and the consequent formation of obnoxious odors in the pipe-stem, usuallj caused bythe mixture of such moisture and nicotine, prevented.

A further object of the invention is to provide a device, such as a suitable valve, located in the pipe-stem or mouthpiece at any suitable place therein adjacent to the smokepassage, whereby the moisture from the mouth of the user Will be practically prevented from entering the smoke-passage of the pipe-stem and the passage-Way kept dry and sweet for .the passage of the smoke and the consequent adhering of the nicotine to the Walls of the passage-Way prevented.

In the accompanying drawings, forming a part of this specification, Figure l is a side elevation of a tobacco-pipe having this improved device attached thereto. Fig. 2 is a top view thereof. Fig. 3 is an end view, on an enlarged scale, of a mouthpiece, showing this improved device attached thereto. Fig. Jiis a sectional view of a portion of the mouthpiece, taken in line a a, Fig. 3, and showing the different positions of the valve. Fig. 5 is an enlarged. detail view of the detachable plug forming the valve-seat and apart of the smokepassage. Fig. 6 is a longitudinal sec tional view of the mouth-tip or valve-casing. Fig. 7 is a detail of the valve-cap. Fig. 8 is a view of the fastening means for securing the valve-cap into position adjacent to the valve-seat; and Fig. 9 is a vieiv similar to Fig. i, showing a modication of this improved device.

Similar characters designate like part-s in all the iigures of the drawings.

This improved device is adapted for attachment to a cigar, cheroot, or cigarette holder or similar device, but for the purposes of this specification it will be herein described in connection with a tobacco-pipe.

The stem J of the tobaccopipe l0 is of any desired construction and preferably has a suitable detachable mouthpiece Il secured thereto in anp7 suitable Way, and to the outer end of which this improved device is adapt-ed to be applied. It will be obvious, however, that the detachable mouthpiece might be dispensed With and the device attached directly to the pipe-stem, if desired, and in this connection it will be understood that the Words stem or pipe-stem, used in the description and claims, are intended to mean any device having a smoke-passage and used in a similar Way as a pipe and With or Without a detachable mouthpiece. The mouthpiece 11 is provided, adjacent to its free end, With interior screw-threads surrounding the usual smoke-passage 12.

The device for preventing the entrance of moisture into the pipe-stem comprisesa suitable valve, protected by a casing terminating the free end of the pipe-stem, and operative to permit the egress of smoke on the suction of the user, but automatically operative to close the smoke-passage when the user ceases to draw on the ste-1n, whereby moisture from the mouth of the user will be prevented from entering such smoke-passage, and in the pre- Vferred form thereof herein shown and described it preferably consists of a cylindrical 9 IOO 15, preferably integrally connected therewith,

to mesh with the screw-threads of the mouthpiece 1l, when such mouthpiece is used, or to be screwed into the end of the pipe-stem. The screw-threads might, however, be dispensed with, if desired, and the stem held by frictional engagement with the walls of the aperture. This plug is adapted to engage and. rest against the free end of the mouthpiece or stem, and is provided with an inclined beveled outer face forming a valve-seat 16. Removably secured by the valve-casing for swinging or oscillatory movement in any suitable way adjacent to the valve-seat 16 is a valve-cap 17 of any suitable construction.

The means herein shown in the preferred form thereof for securing the valve-cap 17 in position adjacent to its valve-seat 16- comprises a hook 18, adapted to project through an aperture in said cap to support the same. This hook has its opposite end, by means of a bulging part 20, resting within a transverse slot or groove 21 formed in the plug.

As a means for removably securing thehook and valve-cap in place ontolthe plug a preferably tubular tip or valve-casing 22 surrounds the valve-cap and is pressed over the hook, and has its inner edge iianged or bent inwardly to engage the annular groove 14 and the concavity of the bulging part of the hook, whereby the valve-cap and hook are prevented from becoming detached.

In order to prevent the valve-cap 17 from swinging too far from its seat, it is provided with lateral ears or projections .23, which abut against the interior wall of the tubular tip or valve-casing 22 when the capswings outwardly, and thus the same is prevented from swinging too far from its seat.

The valve-cap 17 is preferably of somewhat less cross-sectional area than the tip-or valvecasing 22, whereby the smoke can nd egress around the same when t-he cap is resting on its valve-seat, and whereby the smoke will not be retained in that part of the tip or valvecasing in the rear of the cap.

In the use of a pipe or other smokingdevice having this improved device attached thereto the suction of the user will cause the valvecap to raise or swing outwardly, as shown in dotted line in Fig. 4, to thereby permit the egress of the smoke; but when the user ceases to draw on the pipe the suction. ceases, and the cap automatically falls on its seat, and the spittle or moisture usually formed at this period' is prevented from entering the pipestem and mixing with the nicotine.

By this improved device the mixture of the spittle or moisture from the mouth of the user with the nicotine and the consequent accumulation of such mixture upon the walls of the smoke-passage are thereby prevented, and the passage kept sweet and dry for the passage of the smoke and nicotine therefrom.

By keeping the spittle or moisture from entering the passage of the pipe-stem the nicotine is prevented, to a great extent, from clogging up such passage, and is also prevented from adhering to the walls of the passa ge-way and thereby creating obnoxious odors.

This device can be quickly and easily attached to pipes already constructed, if desired, by simply having the wall of the apertured pipe-stem or mouthpiece threaded, or the device may be constructed with a smooth or slightly tapering stem 13, if desired, adapted to be inserted into the ordinary aperture 0f the pipe-stem or mouthpiece.

In the modification shown in Fig. 9 the plug f 13 has its valve-seat so constructed that the valve-cap 17 can extend substantially adjacent to or beyond the mouth of the tip or valve-casing 22, and in this construction the separate means for hinging the cap is done away with, and in` the form shown the valvecap 17 has a neck 40, adapted to rest in the slot 2l of the plug, which slot, however, in this construction preferably extends transversely of only one of the flanges 41, forming the A `cap supported in said casing and provided with lateral ears adapted to engage the wall thereof, substantially as and for the purpose specified.

2. A smoking device embodying a stem, and having a tip or valve-casing adjacent to its outer end; a plug having anv apertured projection adapted to be secured in said stem adjacent to the free end thereof, said plug having a valve-seat, a valve-cap removably supported for swinging movement adj aeent to the valve-seat, and a hook held in place by the casing for removably supporting the valve in position.

3. An attachment for a smoking device, consisting of a plug having' an apertured stem adapted to be secured in the smoke-passage, and provided with a valve-seat; a valve-cap supported for swinging movement adjacent to the valve-seat; and a valve-casing for securing said valve-cap in position.

4. An attachment for a smoking device, consisting of a plug having an apertured stem adapted to be secured in the smoke-passage and having a valve-seat; a valve-cap removably supported for swinging movement adj acent to the valve-seat; means removably secured to the plug for supporting said cap; and a valve-casing surrounding said valve and securing said means in position, substantially as and for the purpose specified.

5. A smoking-pipe embodying a stem having a smoke-passage therein; a plug having anapertured stem adapted to be secured in said pipe-stemadjacent to the free end there- ZIO 1o fmfrom its seat; ay hook supporting seid cap and having a bulging portion resting in the slot of the plug; and e tip or valve-casing Surrounding said cap and having its inner end bent to engage the groove of the ping, substantially as described.
